Abstract: A controller and methods for hybrid operation control of an electric motor in an electric motor system are provided. The controller is configured to receive a speed command for operating the electric motor, measure available voltage on an inverter configured to provide conditioned AC voltage to the electric motor, and determine a winding phase angle difference based on the received speed command and the measured available inverter voltage. The controller is also configured to adjust a phase angle difference between winding voltage commands for the switches of the inverter using the determined winding phase angle difference, and apply the winding voltage commands including the adjusted phase angle difference to the inverter switches to control the electric motor.

Abstract: A system and method of controlling an electric motor using a motor drive controller are provided. The motor drive controller includes a rectifier configured to convert an AC input voltage to a DC voltage, a DC bus electrically coupled to the rectifier, an inverter electrically coupled to the DC bus and configured to generate an AC voltage to drive the electric motor, and a control unit. The control unit includes a sign calculation module configured to determine a polarity of each phase of a reference current command and a compensation module configured to generate a voltage compensation command signal using one of the determined polarities of the reference current command and a measured current, and one of a measurement of DC bus voltage and a constant DC bus voltage value, the voltage compensation signal compensating the drive controller to neutralize a deadtime effect.

Abstract: A motor control system includes an inverter and a plurality of current sensors each positioned in-line between the inverter and a phase coil of the motor. Each current sensor measures the current provided to each phase coil of the motor and provides a signal indicative of each phase current to a controller. In some embodiments, the currents sensors are provided as one or more current sense integrated circuits. A protection circuit protects the current sense integrated circuit from ground bounce by coupling a diode and an opposite facing Zener diode in series between the power supply pin and the ground pin of the integrated circuit.

Abstract: A quick-release automatic tensioning motor base for supporting a motor. The motor is operably coupled to a device to be driven via a drive belt. The motor base includes at least two base brackets and at least one guide rail fixedly coupled between the base brackets. A platform assembly, which supports the motor, is slidably coupled to the guide rail for movement there along. A spring assembly is selectively coupled between the base brackets and fixedly coupled to the platform assembly. The spring assembly applies a biasing force to the platform assembly to maintain a belt tension along the drive belt. A quick-release assembly selectively engages the spring assembly and the at least two base brackets to permit movement of the quick-release assembly between a first position to retain the spring assembly and a second position to release the spring assembly to permit movement of the platform assembly.
